To LZZ whom, it may concern/.1

Be it known that I, SAMUEL` D. CHAMBERS, a citizen of the United States, residing at War ren, in the county ofv Clay and State of North Carolina, have inventeda new and useful Calendar, of which the following is a specification.

The invention relates v'to improvements` inv calendars.

rlhe object of the present invention is to improve the construction of calendars and to provide a simple and comparatively inexpen- 1 sive one adapted to indicate the month, the

day of the month, and the day ofthe week and capable of enabling the indicating means to be successively advanced and of simultaneously sounding an alarm.

A further object of the invention is to provide a calendar of this character which will be especially adapted for use in hotels, inns, and the like and capable of enabling the alarm mechanism to be operated independently of the indicator-advancing means, so

,that the said alarm may be sounded at any `hour o r time for arousing the inmates of a room or for any other purpose.`

The invention consists in the construction and no vel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is an elevation of a calendar constructedin accordance with this invention. Fig. 2 is a vertical longitudinal sectional View. Fig. 3 is a vertical transverse sectional View.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a casing open at the front and rounded at the top, asshown; but the said casing may be of any other, desired construcits upper face arranged in the same plane as the top of the disk or plate 4, and the arm eit-` tends to the bottom of the same, forming an inner wall to the groove 6. The dials or rings 7 and 8, which are separated by a spacingring 9, are capableof rotation to adjust them to bring different portions of their outer faces at the top of the calendar. The dial or ring Y3, which is of greater diameter than the dial or ring V7, extends beyond the same and is provided at the outer face of its exten ded portion with the names ofthe months,as clearly dial or ring '7 is adapted to be rotated torarg range itV properly for indicatingy the day of` the week the first day of the month falls upon. The stationary dial or disk 4 is provided with a series of numerals ranging from 1 to 31 for indicating the day of the month, and the numeral .1 is located at the top of the calendar, as shown. The day 'of the month is designated by a rotary indicator or hand lO, mounted on a central shaftll, journaled in suitable bearings of the kdial or disk 4and the back ofthe casing and provided with a ratchet-wheel 12, adj ustably mounted on the shaft and located in rear of the said dials. The ratchet-wheel is engaged by an upright pawl13, pivoted at its lower end 14 to one arm of the lever 15, which has its other arm provided with a suitable bellhammer 16. The lever 15, which is arranged normally in a horizontal position, is pivoted between its ends on'a suitable support 17,'cons'isting of a pin or'pivot mounted on a bracket or support that is secured to the back of the casing. The pawl 13, which engages the teeth ofthe ratchet-wheel, has an elongated head 18, provided with a shoulder for engaging the teeth ofthe ratchet-wheel and having an inclined upper face located adjacent to a guide 19, which consists of fanl antifriction roller or sleeve and which is adapted to throw the pawl away from the ratchet-wheel when the IOO arm 20 of the lever 15 is swung'downward Y from a horizontal Vposition for .the purpose hereinafter described. The pawl is pressed inward by a spring 2l, mounted on the pivot of the lower end of the pawl and having a loop for engaging the latter, and when the arm 22 of the lever is swung downward from a horizontal position the pawl engages the ratchet-wheel and rotates the same the distance of one tooth, which is su fcient to carry the hand or indicator from one numeral of` the stationary dial to the next. The movements of the lever are limited by stops 23 and 24, arranged, respectively, beneath the arms 20 and 22. The arm 22 is connected with an operating-cord which passes over pulleys 25 and 26 and which is adapted to operate the lever to advance the hand or indicator. This movement also carries the bell` hammer, which is resilient, into engagement with the bell to sound an alarm when the calendar is changed. The guide-wheel 25 is located directly beneath the point where the cord 27 is attached to the horizontal lever, and the guide-pulley 26 is centrally arranged. The other arm 20is connected with an operating-cord 28,which passes overguide-pnlleys29.A

-andBO and adapted to be operated toswingi the arm 2O downward to carry the bell-ham merinto contact with the bell for soundingl an alarm, and the lever is adapted to lbe op-y erated in this manner without actuating thei ratchet-Wheel, as the pawl by suchmovement is carried upward and away from the said; ratchet-wheel. The guide pulley 29 is lo-i cated beneath the'arm 2O of the horizontal lever, and the pulley 30 is arranged at the center,behind the guide-wheel 26. The move-Q ment of the operating-lever that is eiected by the cord 2S is less than the movement im-` parted to the lever by the cord 27, and the stop 23 is arranged closer to the lever than the stop 24.-. The cords may extend to any desired point, and the calendar may be arranged in the oce or in the respective rooms of a hotel, inn, or the like, and the alarm may-be employed for calling bell-boys or for arousing the occupants of the rooms.

The dials or rings 7 and 8 are provided with suitable grips or handles 3l and 32 to enable them to be readily adjusted, and the dial 7is provided with a slot 33, extending around the dial a distance equivalent to the space occupied by the characters indicating the days of one week and receiving a pin 34, which forms. a stop for limiting the movement of the dial. This will be sufficient to enable the dial to be adjusted to bring any day of the week at the top of the calendar. The dial 8 is also preferably `provided with numerals indicating the number of days in the various months.

What I claim isl. A calendar provided with a movable indicator, an alarm, mechanism for actuating the indicator and for sounding the alarm, and operating mechanism connected with the said mechanism and capable of operating the same to simultaneously change the calendar and sound the alarm and also to sound the alarm without actuating the indicator, substantially as described.

2. A calendar having a movable indicator, an alarm, a lever provided with means for actuating the indicator and for sounding the alarm, and two independent operating means connected with the level-.and adapted, respectively,to si multaneously actuate the indicator and sound the alarm and to sound the alarm without operatin g the indicator, substantially as described.

3. A calendar having a movableindicator, a ratchet connected with the indicator, an

alarm, a leverfulcrumedlbetWeen-its ends and provided at one of its arms `with meansfor soundiugfthe alarm and having a pawl-atiits otherarm for engaging the ratchet-wheel, and operating mechanism connected with the arms of the lever and adapted respectively to simultaneously operate the indicator and sound the alarm and to operate ithe `alarm `without actuatingthe indicator, substantially as described.

4. A `calendar having-a movable indicator, a ratchet-wheel connected with 'theisame,a lever fulcrumed between Vits ends, a Vpawl connected with the lever and engaging the ratchet-wheel, a bell-hammer mounted on the `other arm of the lever and adapted to sound an alarm, operating mechanism connected posed face, a guide arranged to be engaged' by the face to throw the pawlaway from the ratchet-wheel, an alarm having its operating means connected with the lever, and independent operating means connected with the arms of the lever, substantially as described. In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.
